(1) For the three-month period ended March 31, 2013, earnings were insufficient to cover our fixed charges by $42.2 million primarily due to non-cash expenses, including amortization expense from acquired intangible assets and adjustments to revenue as a result of the application of purchase accounting for the Transaction.

(2) For the period from December 29, 2012 through December 31, 2012, earnings were insufficient to cover our fixed charges by $104.0 million due primarily to transaction-related costs, additional amortization expense from acquired intangible assets and stock-based compensation.
